Subject: for %{arm} with hardfloat pass -mfloat-abi=hard to clang invoked by bindgen
X-Git-Tag: auto/th/Mesa-22.3.0-1
X-Git-Url: https://git.pld-linux.org/?a=commitdiff_plain;h=958c933ebc086e0e568bc061cb651f89213699d1;p=packages%2FMesa.git

for %{arm} with hardfloat pass -mfloat-abi=hard to clang invoked by bindgen

it appears that libclang preprocessing uses some minimal platform
configuration which for %{arm} means soft float causing error on hard
float targets:

/usr/include/gnu/stubs.h:7:11: fatal error: 'gnu/stubs-soft.h' file not found
panicked at 'Unable to generate bindings: ClangDiagnostic("/usr/include/gnu/stubs.h:7:11: fatal error: 'gnu/stubs-soft.h' file not found\n")', bindgen-cli/main.rs:52:36
